Greetingzz :-)

I have a trouble with files which have national (russian-language) characters in filenames. All is ok with files that contain only english characters in name, but when i upload russian-name files there is a trouble.

Server succesfully receives the file and places it in right directory, but when i try to see this file in gallery i receive "image cannot be found" - only redcross and placeholder are shown (this concerns both thumbnail, normal_ and original images).

When i try to go to hyperlink of picture i receive FORBIDDEN and *wrong-encoded* non-original filename of picture in error report (russian characters are encoded to %xx url-replacements, but when i paste this string to browser it returns wrong decoded russian-chars).

Alt text of thumblail and title of image are normal, also filename showing in fileinfo is normall too.

What this can be? Web-server or coppermine? Does anybody have something like this? And what info i must provide?

Really big THANX for great work to all people who take part in CPG development!
Sorry for my bad eng =)

Webserver with my gallery is in lan and doesn't have an internet connection =(
I began an investigation and discovered that image names being encoded into hex-representations of ascii chars (russian windows-1251 charset, i knew it erlier but hasn't made attention) but the browser thinks that URLs are utf-8 encoded and interpreters chars as hex-encoded UTF-8-chars -> decodes filenames into UTF-8, which results in wrong filenames (wrong utf-8 character with same number replaces right ascii char).

So as i think, there is an "coppermine (mysql stores russian data as windows-1251 too?) url-encoding as ascii (webserver returns ascii-encoded urls)" <-> "browser url-decoding as utf-8" trouble.

I can't use disabling "Always send URLS as utf-8" option (and does this have a mention anyway?) and have many users uploading imgs with russian filenames to gallery so i wonder if there are none-client-side solutions for this trouble (an utf-8 url encoding for example)?

***Apache and php have windows-1251 encoding as default.***

Thanx for your support!

is this right to encode windows-1251 filenames in url into utf-8 and then encode those utf-8-filename-urls with urlencode?

[Nightshader]

So i found a solution (i don't know if it is right, i need your advice about this =)) - encoding URLs into utf-8 before rawurlencode.

Changes i made (CPG 1.3.2)

In functions.inc.php:
Found

// Function to create correct URLs for image name with space or exotic characters
function path2url($path)

and inserted before this lines new function

// Function to convert windows-1251 chars into utf-8
function win1251_to_utf8($string)

    $string = ereg_replace(chr(255),chr(209).chr(143),$string); # &#255;
    return $string;
}

then i added the new string (which calls to previously added function) before this string

       return str_replace("%2F","/",rawurlencode($path));
}

this new string is

       $path = win1251_to_utf8($path);

So changed path2url function is

// Function to create correct URLs for image name with space or exotic characters
function path2url($path)
{
        $path = win1251_to_utf8($path);
        return str_replace("%2F","/",rawurlencode($path));
}

That is all the changes i made. Everything seems to be ok - now pictures with russian filenames are shown. Is my code correct? Functions get_pic_url and path2url are only used when displaying images, right?
